Usain Bolt has already reaffirmed his status as the fastest man in the world, and fellow Jamaican Shelly-Ann Fraser-Pryce did the same on the women's side. Even though those titles have been handed out, there are still several intriguing races left to come.
They include an appearance by Lolo Jones—who has been one of the most talked-about Olympic athletes and hasn't even reached her event finals yet—some terrific relays and a couple more appearances by the electric Bolt.
Let's take a look at the most exciting races yet to come and preview the most important storylines heading into each of them.
The aforementioned Jones is the star of this event even though she's not the favorite. Sally Pearson of Australia is the top choice to win gold with American Kellie Wells also being given a better chance to reach the podium.
But it's Jones who's become the center of attention. The polarizing star has both her admirers and detractors, with the latter claiming her individual results don't match the type of attention she receives from the media.
Jones has a chance to put that debate to bed if she can win a medal on Tuesday. She first must qualify for the finals in her semifinal heat, which also features favored Pearson.
Who will win the 200 meters?
Bolt will attempt to match his individual double-gold-medal performance from Beijing with another one in London. Having silenced the doubters with a tremendous run in the 100-meter final, he will go for gold again in the 200 meters.
His toughest competition will again come from countryman and trainer partner Yohan Blake. They posted nearly identical times during the first round of heats and figure to be battling over the final few meters on Thursday as well.
A potential wild card is another Jamaican, Warren Weir. He posted a faster qualifying time in the opening round than both Bolt and Blake and will be looking to steal the spotlight. He'll need to run a perfect race to beat them in the final, though.
Both 100-meter relay events are setting up as match races between the United States and Jamaica. On the men's side, the Jamaicans are favored, and the American women are favored on the other side, which sets up for two thrilling gold-medal runs.
The combination of Bolt and Blake will be incredibly difficult to beat given their track record and performance so far. The Americans do have enough depth to at least put a scare into the Jamaicans, led by 100-meter bronze medalist Justin Gatlin.
In the women's 100-meter race, the top five finishers were either from the United States or Jamaica. It will be nearly impossible for another team to keep up with that type of talent in the relay, but the race between the two top teams should be incredible.
